assuming this is not a reboot it might have something more to do with continuity from a business standpoint. I e Hasbro would be apprehensive of jumping ship with Paramount if they have a new movie that is sort of kind of tied to the old ones. Makes the entire process a lot more difficult for Hasbro and the franchise to leave Paramount. Of course if that turns out to actually be the case than Paramount are a bunch of assholes. Of course I'm just speculating here please don't take this seriously.
